Please elaborate what is CRS gain in LTE
RegardsDear Expert,

I'm facing a issue in 4G ZTE. Handover from 4G(900-3Mhz) to 3G(900-2100) is very bad. HOSR is 89%. The main reason is "Number of Re-estabilshment to Source eNodeB When Outgoing inter-RAT(LTE-&gt;UTRAN) Handover Execution" (C373312713). 3G side is normal (no congestion, no alrm....). This issue happended on wholoe network. Please give a suggestion to solve this cause. Thanks for your help!

So i have wondered if the UE still be able to do re-establishment for such a case after outage period?

In the normal flow after UE is RACH to the cell B (After previous cell is off) and Reest request to cell B(MSG3) Cell A need to send HO req to cell B but this case, for cell A signal is completely outage.
